I can't say what is causing her diarrhea, but to start I would stop feeding the dry food. You can try plain white rice and boiled hamburg until her digestive tract calms down.
If the diarrhea is uncontrolable, I'd stop feeding solids and try some Pedialyte for a day. If it continues, I'd call the vet. You don't want her to get dehydrated.
You can check for dehydration by pulling up on the skin, it should snap back, if it stays in place, she's dehydrated.
I don't think it has anything to do with the crate size.
Hope she feels better soon.
